The Big 12 says errors were made by the referees at the end of regulation before No. 6 Kansas outlasted Iowa State in overtime on Monday night.

The league said Tuesday that "appropriate measures will be taken" against the two officials involved, including an adjustment of "the number of future assignments."

Tom O'Neill, Mark Whitehead and Bert Smith refereed the game, but the he Big 12 did not identify which refs will be reprimanded or the plays in question.

Kansas's Elijah Johnson drove into the lane and got tangled up with Iowa State's Georges Niang with less than 10 seconds left. No foul was called, and Niang was then whistled for fouling Johnson on the floor. Johnson sank two free throws to force OT with 4.9 seconds left.
